And from Milwaukee, some unhappy insect news:
Mick Skwarok, a spokesman for the Department of Agriculture, Trade and Consumer Protection, also said the agency will order a quarantine of Ozaukee County, probably Washington County and potentially other counties before the end of the week as a first step in trying to stop the invasive pest.
The agency is meeting with the U.S. Animal and Plant Health Inspection Service on the quarantine, a tactic used by other states when outbreaks have occurred.
About 750 million trees are at risk in Wisconsin.
Pretty much everything you would want to know about EAB can be found at the Emerald Ash Borer portal.
A brand new paper out in the journal Environmental Entomology describes a possible new method to trap the beetles, using chemicals that their host plant (Ash trees) release:
“In a field test comparing and combining Phoebe oil with Manuka oil, Phoebe oil-baited traps caught significantly more beetles than either Manuka oil-baited traps or unbaited traps.”
The full title of the paper is:
Development of a Host-Based Semiochemical Lure for Trapping Emerald Ash Borer Agrilus planipennis (Coleoptera: Buprestidae)
There is also some bad news in this same issue of the journal–evidence that Japanese Beetles feed plants grown under high CO2 conditions laid more eggs, and lived longer. Damn it.
“Females consuming elevated CO2 foliage laid approximately twice as many eggs as females fed foliage grown under ambient conditions….Although the precise mechanism is unclear, by altering components of leaf chemistry other than sugar content, elevated CO2 may increase populations of Japanese beetles and their impact on crop productivity.”
Also–if you see ads on this page (and you probably will) I have no connection with those. They seem to have multiplied out of control recently. I am investigating getting them stopped, or moving (UGH!) to a new host.
